FOLDING MACHINE.

Application led December 8, 1919.

T0 all whom t may concern:

Be it known that I, EDWARD GUY GoBnN, citizen of the United States, and resident of New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in a Folding Machine. of which the following is a specification.

This invention relates to a folding ma` chine. Its object is the production of a machine vvhich will remove pieces of cloth or other material from the cylinder o-f aprinting press and fold all of them in a similar manner. The folding machine is adapted to operate with the cutting machine described in application, Serial Number 343,391, filed Dec. 8, 1919.

The said cutting machine cuts cloth or other material in equal lengths, for delivery to a printing press, while the present invention removes the cloth or other material from the printing press and delivfrs it folded for further operations.

The folding machine comprises essentially a receiving drum comprising a plurality of receiving wheels secured to a rotary shaft. All of the wheels except one have' connected thereto automatically operated grippers, to grip the material operated upon and draw it from the cylinder of the printing press with which it coacts. One of the wheels of the receiving drum coacts with a releasing device for the grippers. The folding machine also contains a discharging drum, comprising a plurality of discharging wheels carried on a rotating shaft. The latter wheels carry a pinching bar having lingers, by means of which the pieces of material operated upon are drawn from the receiving wheels. By means of a releasing mechanism the lingers of the pinching bar releases the material and it is discharged from the machine in equal folded portions.

The pinching bar with its appurtenances Serial No. 343,390.

on the line 3, 3 with a portion of the folding machine shown in dotted lines and Fig. 4 is a section of Fig. 1 on the lines 4, 4.

The folding machine is indicated with a fragmentary portion of a printing press having the side frames 15 and 16 in which is journaled the shaft 17. A driving pulley 18 and printing cylinder 19 are fastened to the shaft 17. The cylinder is provided with the usual grippers as 20. The supporting beams as 21 of a cutting machine are supported on the side frames 15 and 16. `With the frames 15 and 16 are formed the accompanying pairs of journal bearings 26, 27 and 28, 29. A shaft 30 is journaled in the bearings 26, 27 and on which is fastened a receiving drum R. The drum comprises a plurality of receiving wheels 31 and 31a. Each of the wheels comprises the rim 32 with the spokes 33. A lug 34 extends from the wheel 31a. A circular annular web 35 with the circular annular slot 36 is formed with the wheels 31 and 31a. A gear 37 is fastened to the shaft 30 adjacent to one end thereof and bolts 38, 39 connect the gear 37 with all the wheels 31 and 31a. In the rim 32 of each of the wheels 31, 31a is seated the iinger bar 40 having formed therewith and extending from its outer face the receiving and stationary gripping fingers 41. Screws 42 fasten the bar 40 to the rims 32 of the said wheels. Supports 43, 44 and 45 are fastened to the shaft 30 by means of screws 46. Each of the supports comprises the body portion 47, having the hub 48 at one end, the curved projection 49 at the other end and the hub 50 adjacent to the projection 49. A. hub 51 is formed with the portion 47 of the supports 43 and 44. A buffer support 52 is carried on each of the projections 5() and is held in place by means of a screw 53 and dowel pin 54. A bu'er 55, preferablyv of leather, is fastened in a dovetailed opening in the buffer support 52. A bolt 56 extends through each of the slots 36 of the wheels 31 and 31a and through the hubs 51 of the body portion 47. Nuts 58 at the ends of the bolt 56 hold it in place. On the said bolt 56 are secured the grippers 60 by means of the screws 61.

A stationary cam 62 with the guide finger 63, the cam surface 64 and the vertical leg 64l has formed therewith thq bracket 65'.l The latter is fastened to the frame 16,

by means of thebolt `66. lThe shaft 30 extends througlrthe cam 62 `at the upper portion thereof.

To and in front of the support is pivoted on the bolt 56, the lever having the arms 67 and 68. A cani roller 70 is jour- ,of the stem 74 extends through the opening in the lug 34 of the wheel 31a. A spring 75. encircles the stem 74 and bears between the head 73 and the lug 34.

"A shaft 80 journalled in the journal bearings 28,29 has fastened thereto the discharging drum VD, comprising the discharging Wheels, 81. Each 0f the wheels 81 comprises they rim 82 having the opening 83 and the spokes `84. A gear 85 with the lug 86 is fastened tothe shaft 80, and bolts 87, 88 connect the spur gear 85 and all the wheels 81. A cam is indicated at 89 which has formed therewith the cam surface 90 and the bracket "91. Bolts 92 `secure the bracket 91 to they frame 15. A pinching bar 93 yhaving the fingers 94 and recesses 95, is fastened to each arm 96. The latter are fastened to the *bolt 87.

ln the opening 83 arefastened, to lone of the spokes 84 ofeach of the wheels 81, the presser plate 98 and the supporting plate 99.

The plate 98 is preferably made of softermaterial than the plate 99. The plates are vfastened to each other and to the said spokes 84.bythe"screws 100. A lever having the `arms 101 and'102 is fastened to the bolt 87. A roller 103 is journaled on a pin 104 eX- 'tending from the arm 101, and which is adapted to ride on the cam surface 90. The arm `102 has formed therewith a cavity 105 invvhich extends a pin 106. A head 107 offa stem 108 islocated in the cavity 105. The outer end of the stem 108 extends through: the lug 86 of the spur gear 85. A

:thread 109 is cut on the stem 108` at the in- 11er portion thereof for an adjusting nut 110.`

A spring 112 encircles the stem 108 and bears between the lug 86 and the adjusting nut 110. A gear 115 on the shaft .17 of the .presscylinder 19 meshes with a gear 116 'fastened to the shaft 30. The stem 74 can ybe `threaded for an adjusting nut similar' to the nut. 110.

A prism landing block 120 with the apex .121 and preferably of wood has connected kthereto'the side plates 122, which are fastened to the side frames 15 and 16.

4To operate the folding machine the pulley .18.isturned by means of a belt, not shown, landthe spur gear 115 and cylinder 19 are .caused 'to .rotate in the .direction of the y:arrow A.

`The gear115 rotatesthe spur Q fearl16.y

causing the shaft 30 with thespur gear 3T to rotate, whereby the receiving drum R caused to rotate in the direction of the arrow B. The spur gear 37 rotates lthe spur gear 85. causing the discharging drumD to rotate in the direc-tion of the'arrow C.

The cut pieces of material to be folded are delivered from the cutting machine referred to, by means of appurtenances not shown located between the supporting beams 217 to the printing press cylinder 19. The latter. by means of its grippers 20 carries the material on the` surface thereof in proper position for the appurtenances of the 4iolding machine.

The grippers 60 of the receiving drum li gripthe cut pieces of material immediately after it is released by the grippers 20. and carries them on the rims 32 of the receiving wheels 31 and 31u. The gripper 60 of each wheel 31 can be located in proper position to suit different lengths of cloth or other inaterial 120, by loosening the screws 46.v eX- cepting the one for the support 45 and swinging the drum R'until `the circumferential distance between the fingers 41 and the buffer equals one-half of the length of the pieces of material to be'folded after which the said screws areagain tightened in place. When they roller 70 rides on the cam surface 64 yof the stationary cam 62 the grippers are open, and they will close as soon as the roller reaches the vertical leg l641,by virtue of the tension of the spring 'roller 103 startsto ride onthe stationary cam surface 90'.'and thereby the pinching .bar 93 is swung to its closed position. At `the same time the fingers41 move into the recesses 95 and the fingers 94 grip the pieces of material 120. The material is now drawn to. the rims 82 of the wheels 81, ina folded position with a crease formed on the line across the piece of material where it was in .contactwith the receiving and gripping fingers 41.

When the roller 103 leaves the cam Vsurface 90, the pieces of material are releasedby means of the tension of the spring 112. which moves the arms 96 and thereby releases the material from thetingers 94 and the presser plate 98. The folded material or pieces of cut clothare deposited on the landing block 120, the crease of the fold located at the apex 121 of said block.
